Userv allows one program to invoke another when only limited trust exists between them. It is a tool which can be used to avoid having to give other system services root privileges, and which allows users to more securely have programs provide services to others. Userv can be useful as 'glue' for system administrators as well as application authors; there are a few userv-using utilities/examples in the associated userv-utils package.
